这是标签代码:

import {Directive} from '@angular/core';

@Directive({
  selector: '[ngbButtonLabel]',
  host:
      {'[class.btn]': 'true', '[class.active]': 'active', '[class.disabled]': 'disabled', '[class.focus]': 'focused'}
})
export class NgbButtonLabel {
  active: boolean;
  disabled: boolean;
  focused: boolean;
}

这是单选按钮代码:

import {Directive, forwardRef, Input, Renderer2, ElementRef, OnDestroy} from '@angular/core';
import {ControlValueAccessor, NG_VALUE_ACCESSOR} from '@angular/forms';

import {NgbButtonLabel} from './label';

const NGB_RADIO_VALUE_ACCESSOR = {
  provide: NG_VALUE_ACCESSOR,
  useExisting: forwardRef(() => NgbRadioGroup),
  multi: true
};

let nextId = 0;
